Question 1 of 34
1. Question
1 pointsA software engineer is involved in the development of an application. For usability tests, the engineer needs to make sure that the application will work in both Windows 7 and Windows 8 environments. The features and functions must be verified in the actual OS environment. The engineer is using a Windows 7 workstation. What two technologies can help the engineer achieve the usability tests? (Choose two.)Correct
Incorrect
Hint
Client-side virtualization enables a host OS to provide a virtual environment within which a guest OS can be installed and be operational as an actual OS. The dual boot configuration will provide an option to run either OS (but not both at the same time). Just using two disks is not a sufficient solution to run two separate OS. -
Question 2 of 34
2. Question
1 pointsWhich two business and technical challenges does implementing virtualization within a data center help businesses to overcome? (Choose two.)Correct
Incorrect
Hint
Traditionally, one server was built within one machine with one operating system. This server required power, a cool environment, and a method of backup. Virtualized servers require more robust hardware than a standard machine because a computer or server that is in a virtual machine commonly shares hardware with one or more servers and operating systems. By placing multiple servers within the same physical case, space is saved. Virtualized systems still need the proper licenses for operating systems or applications or both and still need the proper security applications and settings applied. -
Question 3 of 34
3. Question
1 pointsWhat are two advantages of using PC virtualization? (Choose two.)Correct
Incorrect
Hint
Benefits of virtualization include cost savings, the use of multiple operating systems on a single PC, and isolation for software testing. -
Question 4 of 34
4. Question
1 pointsA small company is considering moving many of its data center functions to the cloud. What are three advantages of this plan? (Choose three.)Correct
Incorrect
Hint
Cloud computing offers many advantages to the company. Since the cloud data storage and processing facilities are owned by third-parties, the company does not need to be concerned about how it will handle increasing data storage and processing demands with its own data center equipment. The company can easily increase or decrease processing power and storage capacity based on need. Also, cloud services are billed by usage, so the company does not have the costs of supporting its own expensive data center that is not always used to maximum capacity. -
Question 5 of 34
5. Question
1 pointsA college uses virtualization technology to deploy information security courses. Some of the lab exercises involve studying the characteristics of computer viruses and worms. What is an advantage of conducting the lab exercises inside the virtualized environment as opposed to using actual PCs?Correct
Incorrect
Hint
Virtualization can create a controlled environment that is isolated from external networks. Because of shared system resources, the performance inside a virtual environment will not be faster. However, the benefit is that a virtual environment provides a safe platform for information security analysis. -
Question 6 of 34
6. Question
1 pointsWhat technology allows users to access data anywhere and at any time?Correct
Incorrect
Hint
Cloud computing allows organizations to eliminate the need for on-site IT equipment, maintenance, and management. Cloud computing allows organizations to expand their services or capabilities while avoiding the increased costs of energy and space. -
Question 7 of 34
7. Question
1 pointsTrue or False. Cloud computing and virtualization are different terms that refer to the same thing.Correct
Incorrect
Hint
False. Although the terms cloud computing and virtualization are often used interchangeably, they actually mean two different things. Virtualization is a component within cloud computing that separates the operating systems from the underlying hardware, whereas cloud computing separates the application from the hardware. -
Question 8 of 34
8. Question
1 pointsHow does virtualization help with disaster recovery within a data center?Correct
Incorrect
Hint
Live migration allows moving of one virtual server to another virtual server that could be in a different location that is some distance from the original data center. -
Question 9 of 34
9. Question
1 pointsWhich type of hypervisor would most likely be used in a data center?Correct
Incorrect
Hint
The two type of hypervisors are Type 1 and Type 2. Type 1 hypervisors are usually used on enterprise servers. Enterprise servers rather than virtualized PCs are more likely to be in a data center. -
Question 10 of 34
10. Question
1 pointsWhat is the main function of a hypervisor?Correct
Incorrect
Hint
A hypervisor is a key component of virtualization. A hypervisor is often software-based and is used to create and manage multiple VM instances. -
Question 11 of 34
11. Question
1 pointsWhich statement describes a characteristic of cloud computing?Correct
Incorrect
Hint
Cloud computing allows users to access applications, back up and store files, and perform tasks without needing additional software or servers. Cloud users access resources through subscription-based or pay-per-use services, in real time, using nothing more than a web browser. -
Question 12 of 34
12. Question
1 pointsA technician needs to use an application that is not supported by Windows operating systems on the PC. How can the technician make this application run on the PC?Correct
Incorrect
Hint
Windows Compatibility mode will only allow an application to run as long as it is supported by the Windows operating system. The application cannot be installed if the operating system does not support it. It is necessary in this case to create a virtual machine with an operating system, as the guest OS, that supports the application. -
Question 13 of 34
13. Question
1 pointsWhich Cloud computing service would be best for an organization that does not have the technical knowledge to host and maintain applications at their local site?Correct
Incorrect
Hint
Software as a Service (SaaS) allows a business to host an application through a Cloud provider. The Cloud provider manages access to the application and maintains the application. The application can be utilized by any authorized device with an Internet connection. -
Question 14 of 34
14. Question
1 pointsWhat is a difference between the functions of Cloud computing and virtualization?Correct
Incorrect
Hint
Cloud computing separates the application from the hardware. Virtualization separates the OS from the underlying hardware. Virtualization is a typical component within cloud computing. Virtualization is also widely used in data centers. Although the implementation of virtualization facilitates an easy server fault tolerance setup, it is not a fault tolerance technology by design. The Internet connection from a data center or service provider needs redundant physical WAN connections to ISPs. -
Question 15 of 34
15. Question
1 pointsWhich is a characteristic of a Type 1 hypervisor?Correct
Incorrect
Hint
Type 1 hypervisors are installed directly on a server and are known as “bare metal” solutions giving direct access to hardware resources. They also require a management console and are best suited for enterprise environments. -
Question 16 of 34
16. Question
1 pointsWhich is a characteristic of a Type 2 hypervisor?Correct
Incorrect
Hint
Type 2 hypervisors are hosted on an underlaying operating system and are best suited for consumer applications and those experimenting with virtualization. Unlike Type 1 hypervisors, Type 2 hypervisors do not require a management console and do not have direct access to hardware. -
Question 17 of 34
17. Question
1 pointsWhich cloud model provides services for a specific organization or entity?Correct
Incorrect
Hint
Private clouds are used to provide services and applications to a specific organization and may be set up within the private network of the organization or managed by an outside organization. -
Question 18 of 34
18. Question
1 pointsWhich type of Hypervisor is implemented when a user with a laptop running the Mac OS installs a Windows virtual OS instance?Correct
Incorrect

1 pointsA training company offers many application courses based on Windows. The company is looking for a solution to provide a hands-on learning and practice environment to remote learners. The goal is to provide a uniform learning environment to all users. Which cloud-based solution would help the company to achieve the goal?Correct
Incorrect
Hint
Virtual desktop infrastructure (VDI) can be used to deploy entire desktop environments from a server in a data center to clients. VDIs can be persistent, which provides the user with a customizable image that is saved for future use, or non-persistent, which reverts the image back to its initial state when a user logs out. -
Question 20 of 34
20. Question
1 pointsA small college wishes to deploy a leaning management system (LMS) and is looking for a hosted solution. Which type of cloud-based solution would help the college to achieve the goal?Correct
Incorrect
Hint
The cloud-based virtual application stream, or cloud-based applications, can provide on-demand software application delivery to end users. In the case of LMS, when a user needs to use the web-based service, the user will open a client (web browser) to access the system. Minimal application code is then forwarded to the client based on the information the user needs. -
